This antenna is designed for ceiling mounting and comes with two installation options, depending on whether you have access to the space above the ceiling.

If you have crawl space or attic access:
Drill a 20 mm hole in the ceiling, then feed the antenna’s cable through. From above, thread the included fixing nut onto the antenna’s base to secure it in place. Connect the N-Female connector to your SC-400 cable and route it to the booster’s “Inside” port.

If crawl space access isn’t available:
Drill the same 20 mm hole for the cable, then use the included mounting plate. Mark and drill holes for the provided anchors, then attach the metal bracket to the ceiling. Push the antenna into place, aligning its keyhole mounts with the pegs on the bracket, and twist to lock. Connect your SC-400 cable and route it to your booster.

Installer tips:

• Keep at least 20 feet of vertical or horizontal separation between this inside antenna and your outdoor antenna
• Avoid placing the antenna near large metal objects, HVAC ducts, or thick walls
• Do not coil excess cable near the booster — lay out cable runs cleanly

This antenna is rated for indoor use and performs well in offices, warehouses, and commercial spaces, even in challenging environments with heat or humidity.
